The U.S. military conducted a strike on a vessel in the Caribbean Sea on Wednesday, killing four people accused of drug trafficking operations, according to U.S. Southern Command.

The military command, which oversees operations in Latin America and the Caribbean, announced on social media that it had carried out a "lethal kinetic strike on a vessel operated by Designated Terrorist Organizations." The strike was conducted by Joint Task Force Southern Spear on March 25.

According to Southern Command, the targeted vessel was transiting along known narco-trafficking routes in the Caribbean and was engaged in drug-trafficking operations. The military described those killed as "narco-terrorists" but did not specify which designated terrorist organization was operating the vessel.

The strike represents the latest action in what U.S. Southern Command has described as efforts to apply "total systemic friction on the cartels." The command oversees U.S. military operations across Central and South America as well as the Caribbean region.

Further details about the specific location of the strike, the type of vessel targeted, or the circumstances leading to the military action were not immediately provided by Southern Command officials.
